GridView positions at wrong index and displays delegates out of position when setting position when resizing

When GridView is being repositioned, after loading it, by `positionViewAtIndex` and its size changes at the same time, it positions at wrong place and draws items out of position (sometimes with blanks in between delegates). I checked with list view and it works fine.
I attached "test case" with 2 options (GridView & ListView) to test out, blue button resizes window & component.
On first screenshot you can see element drawn out of order.
